It applies controlled force to bend a specimen, typically a metal bar or sheet, at specified angles and rates to determine its . Built-up cold-formed steel beams fabricated from several single sections exhibit higher bending capacities, and can be designed to eliminate the eccentricity between shear and gravity centres and to feature new shapes to fit the particular application including shapes with closed loops and greatly enhanced torsional rigidity.2.1 Pyramid Rolling or Cold Bending. Cold bending using “pyramid rollers” is a common curving technique used to create HSS members with a constant radius. The method involves running the member through between three rollers, oriented in a pyramid shape as shown in Figure 1, varying the distance between the rolls with successive passes.
An increasing number of cold-formed thick-walled members are being employed in engineering structures. However, research on their bending performance is still lacking, and existing codes are primarily suitable for thin-walled steel members. Therefore, bending tests were conducted on 10 cold-formed thick-walled rectangular beams.
